These templates are mainly adopted from the existing Cacti ones.
Currently, only MySQL template is available.

There are a few major differences between Cacti and Zabbix templates:

Zabbix does not support negative Y axis, that’s why you can see the negative
values on some graphs to work out that - consider them the same as positive ones.

Zabbix does not support stacked graph items with mixed draw styles, that’s why
some graphs may not look so nice like in Cacti as the stacks are replaced with lines.

Other Zabbix specific points:

The items are populated by polling Zabbix agent.

There are predefined triggers available to use.

There is a screen as a placeholder for all graphs.

300 sec. polling interval - like with Cacti, the existing PHP script is used to
retrive and cache MySQL metrics except some trigger-specific items. Due to the
caching of results, PHP script runs only once per period.
